AIR-ANT2524DB-R Datasheet
Overview
The next generation of Cisco Aironet 802.11n access points -the Cisco Aironet 3600e Series and 1550 Series requires the use of dual-band external antennas to make them fully functioning units. As these access points take greater advantage of the multiple-input multiple-output (MIMO) features supported under the 802.11n standard, the number of radio transceivers per frequency band has increased. Using dual-band antenna ports allows the access point to support these added transceivers while maintaining a reasonably low number of antenna connections. Each dual-band antenna can transmit or receive Wi-Fi signals in both the 2.4-GHz and 5-GHz bands simultaneously.

AIR-ANT2524DB-R Datasheet System Requirements
This antenna is designed for use with Cisco Aironet access points that support simultaneous operation in the 2.4 GHz band and the 5 GHz band and that have dual-band antenna ports, labeled in orange text. The Self Identifying Antenna model AIR-ANT2524DW-RS= is supported only on Cisco Catalyst 9800 Series Wireless Controllers running an IOS-XE 17.4.1 release or a later release. This antenna model is not supported on Cisco AireOS Wireless Controllers.
Features
The antenna has an articulated base that can be rotated 360 degrees at the connection point and from 0 to 90 degrees at its j oint. The AIR-ANT2524DW-RS antenna includes circuitry to enable self identification of the antenna by the Cisco Catalyst 91xx Series access points. The self identifying function is indicated by a purple band on the antenna. Ensure this antenna is connected to Port A on the AP, which is also designated by purple text around the RP-TNC connector. This antenna has a built-in EEPROM that can be read by the AP to automatically configure the antenna type and gain in the Wireless LAN Controller.
Installing the Antenna Caution: The AIR-ANT2524Dx-R series of antennas are dual-band antennas, meaning that they operate in both the 2.4 GHz and 5 GHz frequency bands. The AIR-ANT2524Dx-R series antennas have an orange ID band on them to indicate their dual-band functionality. Connect these antennas only to dual-band antenna ports, which are identified with orange text on Cisco Aironet access points. Using these antennas on Cisco Aironet access poi nts that employ single-band antennas might result in lower performance. To install the antenna: 1. Verify that the connector to which you are connecting the antenna is a dual-band antenna port, identified by orange text on the access point. 2. Align the antenna connector with the RP-TNC connector on the access point. 3. Engage the antenna connector threads with the RP-TNC connector on the access point. 4. Hand tighten the antenna to the port using the metal knurled ring only. Warning: Do not use the plastic body to tighten. This may damage the antenna. 5. Adjust the antenna articulating joint to the desired position.
